The result is weakened collagen fibres, reduced skin elasticity, faster skin ageing and joint pain. That is why it is necessary to regularly replenish the resulting deficiencies of this protein, preferably with the help of high-quality fish collagen.

Fish collagen – what it is and what types there are 

Fish collagen, like other forms of collagen, is a protein naturally produced by many organisms; in humans, it accounts for nearly 30% of all proteins. It is the most important building material of connective tissue, and when we refer to fish collagen, we mean collagen synthesised from the skin, heads, tails and bones of fish. Its characteristic feature is somewhat less dense bonding between the fibres, which means that it dissolves better and is absorbed more quickly by our bodies. There are two basic types of fish collagen: 

  • type I, which affects the condition of the joints, bones, hair, nails, skin and cornea;
  • type II, responsible for the formation of articular cartilage and the amount of synovial fluid. 

Fish collagen – symptoms of its deficiency 

Any collagen deficiencies must be promptly replenished with properly selected fish collagen, whose structure most closely resembles that of human collagen. Deficiencies cause symptoms such as: 

  • increased susceptibility of the skin to damage;
  • joint pain and stiffness;
  • limited joint mobility;
  • weakened hair and nails.

Fish collagen – medical and cosmetic effects

This type of collagen is finding increasingly broad medical and cosmetic applications, thanks to its numerous properties and ease of obtaining it, especially marine collagen derived from fish species such as shark, cod and tuna. The most important effects of fish collagen include: 

  • support for the immune system; proper levels help protect the body against toxins and pathogenic microorganisms; 
  • more effective protection of internal organs against damage; 
  • improved skin health and appearance; it has fully earned the name “protein of youth”, inhibits skin ageing processes, increases its hydration, firmness and elasticity, and smooths wrinkles; 
  • activation of fibroblasts, the cells responsible for collagen production in the body; 
  • strengthening weakened hair, preventing breakage and brittleness and, consequently, accelerated hair loss; 
  • accelerated skin regeneration and healing of wounds and burns, as well as reduced scar visibility; 
  • a beneficial effect on joint health and condition, improving their mobility, preventing the loss of synovial fluid and alleviating the symptoms of rheumatoid arthritis. 

Fish collagen – which one will be best

There are several forms of fish collagen with which we can replenish its deficiencies in the body. Collagen for drinking is recommended above all, either in liquid form or as a powder to mix with water, as well as in tablet form. Liquid collagen is the better choice; it is very often combined with other essential nutrients, vitamins, including vitamin C, which is necessary for collagen synthesis, and minerals.  

This form is not only more easily absorbed, but also does not burden the stomach as much as tablets. Properly selected doses of collagen can also be found in many cosmetics, especially dermocosmetics, creams for everyday facial care, as well as shampoos and hair conditioners. 

Fish collagen – contraindications and side effects

The use of fish collagen is generally safe, but in some cases it may cause individual allergic reactions, muscle and joint pain or digestive problems, such as constipation. This usually happens when it is overdosed or the recommended daily dose, which is a maximum of 4000 mg, is exceeded. Fish collagen is also safe for children, but pregnant women should consult a doctor before using it.
